CLOCK.

Application filed April 24, 1926. $eria1 No. 104,479.

My present invention has to do with clocks, and its object is the provision of a simple, durable and reliable clock embodying rotary disks instead of hands and designed to be used to advantage in automo-- biles.

Other objects and practical advantages of the invention will be fully understood from the following description and claim when the same are read in connection with the drawings, accompanying and forming part of this specification, in which Figure 1 is a front elevation of the clock constituting the preferred embodiment of my invention.

Figure 2 is a front elevation of the clock as the same appears when the face plate shown in'Figure 1 is removed.

Figure 3 is a vertical central section of the structure shown in Figure 2. p

Figure 4 is a rear elevation of the said structure. a

Figure 5 is a top plan view of said structure with a portion in horizontal section, the sectional part being taken in the plane indicated by the line 55 of Figure 2.

Figure 6 is a horizontal section taken in the plane indicated by the line 66 of Figure 2.

Similar numerals of reference designate corresponding parts in all of the views of the drawings.

The face plate 1 shown in Figure informs part of a casing in which the structure shown in Figures 2 to 6 is disposed, and it wilt be noted from Figure 1 that the said face piate 1 is provided with sight openings disposed one above the other spaced re lation.

The structure shown in Figures t 6 is secured in any appropriate manner in the casing-alluded to, and among other elements the said structure includes a frame 4011 the forward side of which are brackets 5, 6, '8"

and 8, arranged one above the other in spaced relation, Figures 2 and 3. t will also be noticed that the upper bracket 8 is surmounted by an upright 9 "and that the said upright 9 is equipped at its forward side with a pendent resilient detent 10. This detent 10 is for cooperation with .a wheel or disk 11 having rounded teeth 12, Figure 5. The said disk 11 is fixed to an upright shaft 13 'journaled in the brackets 7 and 8, and

fixed to the said shaft 13 is the hour wheel 14 of my improvement, the said hour wheel it unnecessary to illustrate.

14 being providednpon its periphery with hour numerals arranged in regular sequence, Figure 2, and designated by 15, and located to be displayed in succession through the before mentioned sight opening 2.

Manifestly the detent 10 in cooperation with the toothed disk 11 will preclude too free turningof the wheel 14 and will assure the said wheel 14 resting at all times with one of its numerals in registration with the sight opening 2.

Fixed to the shaft 13 and disposed below the wheel 14 is a ratchet disk 16, and arranged toengage the said disk 16 is a dog 17 carried by a spring arm 18, as best shown in Figure 6. The spring arm 18 is connected at 19 to a rcciprocatory member 20, guided at 21 on the frame 4, and it will be noted by particular reference to Figure 4 that the said reciprocatory member 20 is connected to one arm 22 of a bell crank that is fulcrumed at 23 and is provided with a comparatively long arm 24 that is subject to the action of a retractile spring 25 and is equipped with a lateral pro ection 26. When the free end of the arm 24 of the bell crank is raised, the dog 17 will be moved toward the left in Figures 2 and 6 so as to take a fresh hold on the ratchet disk 16, and when the free end of said arm 24 is suddenly released and is pulled down by the contraction of the s ring 25, the member 20, the spring 18 an the dog 1'1 will be moved toward the right in Figures 2 and 6 so as to turn the ratchet dish 16 the distance of one tooth and thereby present a succeeding number in registration or coincidence with. the opening 2.

The free end of the arm is raised the. purpose indicated through the medi of a cam 2'1", preferably shaped as shown Figure the said cam 27 being fixed er otherwise appropriately mounted on what term the hour shaft 28 of my improvement,

and which hour shaft is designed-to berotated by any conventional or other appropriate clock mechanism which I have deemed I would also have it here understood that when desired the shaft 28 may be equipped with a finger piece, not shown, and may be utilized as a setting post for the proper turning of the wheel 14 as well as the minute wheel designated by 29. At its forward end the shaft or post 28 is provided with a miter gear 30, Figures 2 and 3, and the said gear 30 is arranged in mesh with a similar gear 31 timed to a shaft 82 journaled in the brackets 5 and 6, and which shaft 32 is appropriately fixed to the minute wheel 29, as appears in Figure 3.

The wheel 29 is provided on its periphery with numerals designated by 33 and arranged in regular sequence and designed to indicate minutes. I would also have it understood that the numbers 33 are designed to be displayed in succession through the sight openingS, Figure 1.

It will be apparent from the foregoing that the cam 27 is caused to turn a complete revolution every hour, and that, therefore, at the completion of an hour, the wheel '14- will be turned through the proper part of a revolution so as to present a fresh numeral 15 opposite the sight opening 2 to indicate the new hour. I

The winding shaft of the ciock mechanism alluded to is designated by it) and showlrin Figure 2.

Manifestly my novel wheel clock is extremely simple and inexpensive notwithstanding the fact that it is reliablein oper- -atio'n; and it will also be appreciated that the novel clock is not liable to be efi'ectedby vibration ordinarily present in automobiles, and is not likely to be deranged by shocks and jars.

' Lenses without departure from my invention.

Having described my invention, what' I claim and desire to secure by Letters-Patv Ina, clock and in combination, aminute Wheel, an hour wheel, and means operable by means for rotating the minute wheel for ro- *tating or turning the-hour wheel step by step; the'said means comprising a cam, a ratchet disk fixed to thehour, wheel, a reciprocatory member, a sprmg arm on said member and carrying a dog in engagement with the'ratchet disk, a bell crank having an arm connected to said reciprocatory member and also having an arinwwith a portion opposed to said cam, and spring means for holding said arm portion in contact with the cam.

In testimony whereof I afiix my signature.
